What’s different
Chrome extensions
Zen uses Firefox add-ons. Dawn is built on Chromium and installs from the Chrome Web Store.
Imports Arc as it is
Zen can’t import from Arc yet, so Arc’s pinned tabs usually arrive there as plain bookmarks. Dawn brings Arc’s spaces and pinned folders over as they are.
Netflix and Spotify play
Zen has no Widevine license, so Netflix, Disney+, and Spotify’s web player don’t play in it. They do in Dawn.
Where Zen wins
It’s open source and runs on Windows and Linux too.
Switching from Zen?
Dawn brings over your bookmarks in one click.

Zen and Dawn: questions
What comes over from Zen?
Your bookmarks, from the Zen profile you used last. Dawn doesn’t read Zen’s spaces and pinned tabs yet, so bookmark them first if you want them in Dawn.
